This Guru Ball is a mobile treat dispenser to keep dogs busy and occupied. Kibble is loaded into the inner ball where it must then make its way from the inner ball to the outer ball and then out the final treat hole for the reward. It's a simple yet challenging toy! The dog must roll and paw at the ball until all the kibble is gone. The material is durable yet gentle on floors. Our mission is to challenge, engage and inspire dogs by fulfilling their natural instincts by providing activities that help give dogs a purpose each day by keeping them busy, engaged and occupied.
